Answer:
y = 5 ; x = 4
Step-by-step explanation:
Given :
5x + 6y = 50 - - - (1)
x - 6y = -26 - - - (2)
From (2)
x = - 26 + 6y
Put - 26 + 6y for x in (1)
5(-26 + 6y) + 6y = 50
-130 + 30y + 6y = 50
-130 + 36y = 50
-130 - 50 = - 36y
-180 = - 36y
y = 180 / 36
y = 5
Put y =5 in x = - 26 + 6y
x = - 26 + 6(5)
x = - 26 + 30
x = 4
y = 5 ; x = 4
Answer:
1 Expandir.
-28=-21x-28+21x
−28=−21x−28+21x
2 Simplifica -21x-28+21x−21x−28+21x a -28−28.
-28=-28
−28=−28
3 Ya que ambos lados son iguales, hay infinitas soluciones.
Soluciones Infinitas
Step-by-step explanation:
By law of the sine we have:
sine (x) / 38 = sine (35) / 22
Clearing we have:
sine (x) = (sine (35) / 22) * (38)
x = asine ((sine (35) / 22) * (38))
x = 82.18949277
Rounding:
x = 82.2 degrees
Answer:
The answer for this case is given by:
x = 82.2 degrees
option 4
Fourth = 0.25
then
500*0.25=125
125*3=375
Answer: filled 375 seats.
2y = 8x + 6
y = 4x + 3
The graph is a straight line passing through points (0, 3) and (-3/4, 0) with slope = 4.
